Cause
A028
The position of an encoder (motor encoder or
external encoder) was incorrect for one or

more samplings. This can result from EMC
faults or a loose contact.
When faults start to occur at a certain rate,
fault message F51 is triggered by the
corresponding fault variable.
A029
The parameterized limit value for the I2t
monitoring of the motor has been exceeded.

A032
An overflow has occurred during recording

A033
The positive or negative maximum speed has
been exceeded.

Counter-measure
For test purposes, fault message F51 can be
triggered with the setting P847=2 in order to
obtain more information about fault variable
r949.
All indices can also be monitored in r849 in
order to find out which diagnostics counter
counts the fault. If alarm A28 is hidden for this
fault, then the corresponding index in P848
can be set to 1.
Motor load cycle is exceeded!
Check the parameters:
P382 Motor Cooling
P383 Mot Tmp T1
P384 Mot Load Limits
Repeat recording with lower amplitude
- Increase relevant maximum speed
- Reduce regenerative load (see FD 480)
Check
- whether an excessive torque requirement is
present
- whether the motor has been dimensioned too
small.
Increase values P792 Perm Deviation Frq/
set/actual DevSpeed and P794 Deviation Time
Check brake checkback (see FD 470)
Check brake checkback (see FD 470)
Check
- whether the drive is blocked
- Whether the drive has stalled
P690 SSCI AnaIn Conf
- Check slave.
- Check cable.
Check parameter P693 (analog outputs), P698
(digital outputs). Check connectors
K4101...K4103, K4201...K4203 (analog inputs)
and binectors B4100...B4115, B4120...B4135,
B4200...B4215, B4220...B4235 (digital inputs)
for connecting.
Adjust the baud rate in conjunction with the
